APPARATUS FOR LINING CAN ENDS.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed January 31, 1918. Serial No. 214,695.

To all whom it may concern Be it known that I, IVAN D. T HORNBURGH, a citizen of the United States, residing at the city of Berkeley, in the county of Alameda and State of California, have invented certain new and ,useful Improvements in Apparatus for Lining Can Ends, of which the following is a specification.

The hereinafter described invention relates to an apparatus for applying paper pulp or similar semi-fluid material to the flange of a positioned can end for the forming of. a fibrous gasket liner relative to the flange thereof; the object of the invention being to provide a simple, effective, and economical working apparatus for the de-' livery of paper pulp to the flange of a posi-' tioned can end and the hardening or drying of the said pulp so delivered to the said flange as to cause the forming of an applied paper gasket liner for preparing the can end for future use in the canning art for the hermetic sealing of can bodies.

In its preferred embodiment, the apparatus comprises a rotatable reservoir adapted to contain a body of paper pulp, means associated therewith for automatically feeding or controlling the discharge of the pulp from the reservoir onto the flange of av positioned can end, with means for imparting rotary movement to the positioned can end, and means for automatically successively delivering can ends fr m a stack into position for receiving onto the flange thereof the pulp discharged from the pulp holding reservoir, the pulp being uniformly and automatically deposited onto the flange of the revolving can end and the supply of pulp being automatically cut off after the can end has received the requisite quantity of pulp onto the flange thereof for the formation'of a gasket liner.

To comprehend the invention, reference should be had to the accompanying sheets of drawings, wherein,

Figure 1 is a plan view of the apparatus illustrating the rotary carrier for the can end, the end feeding mechanism employed for delivering unlined can ends into position relative to the can end carrier, and the supply pipes controlling air under pressure for the discharging of the paper pulp onto the flange of a positionedcan end.

Fig. 2 is a longitudinal sectional view taken on the line 2-2 of Fig. 1 of the drawings and viewed in the direction of the arrows, illustrating the rotating carrier for the pulp contalneror reservoir, the control valves, the feed mechanism for the unlined can ends, and the air supply pipes and connection.'

Fig. 3 is a broken fragmental sectional plan view taken on the line 3-3 of Fig. 2 of the drawings, illustrating the mechanism for feeding the unlined can ends and positioning the same relative to the rotating carrier, and further illustrating the guides associated with said feeding mechanism for controlling the path of travel of the unlined can ends as moved toward the receiving station relative to the rotating carrier.

Fig. 4 is a fragmental perspective view illustrating the feed control mechanism for the unlined can ends.

Fig. 5 is a longitudinal sectional detail fragmental view'of the pulp and control mechanism, said view illustrating one of the reciprocating plungers of the rotatable carrier for the unlined can end, and one of the air supply nozzles for supplying pulp to the flange of an unlined can end, said view disclosing the controlling valve for the pulp feed so positioned as to cut off the supply of pulp to the feed nozzle.

Fig. 6 is a view similar to Fig. 5 of the drawings illustrating the controlling valve for the pulp supply positioned to uncover the pulp discharge port for admitting the flow of pulp from the discharge nozzle.

Fig. 7 is a view disclosing the parts set forth in Figs. 5 and 6 of the drawings, illustrating the pulp controlling valve as held against movement to prevent the feed of pulp to the discharge nozzle on the absence of an unlined can end to receive the pulp.

.Fig. 8 is a fragmental sectional detail View taken on the line 88 of Fig. 2 of the drawings and viewed in the direction of the arrow, and illustrating the locking mechanism for the pulp controlling valve.

Fig. 9 is a fragmental sectional detail elevation, disclosing two of the pulp lining units.

In -the drawings, reference being had more particularly to Fig. 2 thereof, the numeral 1 is used to designate a suitable supporting frame for the working parts of the apparatus, from which frame rises a stationary drum supporting member 2,

pulp reservoir to the closed by a suitable cover 7, which said cover is provided with a feed opening 8, which is normally closed by a hinged closure plate 9, and it is through the opening 8 that pulp 6' is admitted or introduced into the container 6. The central hub 10 of the container 6 is keyed or otherwise secured to the upper end portion of a vertical shaft 10', which said shaft is journaled at 11 in the supporting member 2 and at its lower end carries a bevel gear. 12 which meshes with a corresponding gear 13 secured to a longitudinally disposed shaft 14, which shaft 14: is suitably mounted in bearings 15 of the frame 1, and the said shaft 14 receives its rotation from any suitable outside source of power, as for instance by a power belt working over a belt pulley 16 secured to one end of the said shaft. It will thus be seen that the power applied to the shaft 14 is transmitted to the pulp reservoir container 6 and the carrier member connected therewith, so as to cause the same to revolve with the motion transmitted thereto, the supporting rollers 4 carried by the member 5 working over the -circular track 3 of the stationary member 2.

An air supply pipe 17 leading from a suitable source of supply, not shown in the drawings, conveys heated compressed air to a suitable air receiving chamber situated within the container or reservoir 6, the said pipe 17 being provided with a control valve 18 and the free inner end of the pipe 17' passing through a suitable stuffing box 19 and communicating with an air pressure chamber 20 formed by 'the inverted cup member 21 fixed to the inner face of the cover 7 of the container or reservoir. By this form of connection between the air supply pipe 1'? and the container or reservoir the moving-elements are free to rotate around the end of the A xed pipe 17, while all times maintaining an air-tight connection between the same and the air pressure chamber 29.

The carrier member 5 is provided with a plurality of spaced circumferentially disposed pockets or seats for receiving and holding in proper position can ends during the pulp lining operation thereof and with each of said pockets there being'associated pulp feed and air feeding mechanisms, so that in the present apparatus there is empioyed or provided a plurality of pulp gasket lining units. inasmuch as each unit of the series is identical in construction, a description of one will suffice for all, it being. understood that an unlined can end is fed to-each receiving pocket at a given position during the-rotation of the carrier member 5 and that with the continued movement of each end while held within its pocket, owing to the continuous rotation of the carrier member 5, the forming or placing of the pulp gasket onto the flange of the positioned can end takes place. lVhen a position of discharge is reached, the gasket lined end is automatically removed, the pulp lining unit therefor continuing in its movement of travel until brought into position relative to the feeding station of the apparatus for receiving a fresh unlined can end, which completes one cycle of operation of the apparatus.

The unlined can end feeding mechanism illustrated in Figs. 2, 3 and 4 of the drawings, comprises a magazine or holder 22, upwardly projected from a suitable supporting member 23, and adapted to contain a stack of horizontally disposed unlined can ends. The holder 22 is provided with a bottom discharge opening 23 and the supporting member 23 of the said holder 22 rests upon the lateral extension 25' of a supporting bracket 25 vertically projected from the frame 1. Where the can ends are of that type which partially project or fit one within the other when in the stacked position and which is the type of can ends herein illustrated, it is required in order to facilitate the easy removal of the lowermost can end from the stack of ends to provide separating means for initially separating the lowermost can end from the stack, and one form of such mechanism is illustrated in l of the drawings. This mechanism comprises a finger 26 provided at its free inner end with an inclined toothed portion 27 the said finger being secured to a rock shaft 28, which is mounted in bearings 29 of the support 23, adjacent to the stack of can ends. The linger 26 is normally held away swung downwardly from the stack of unlined can ends by means of a spring hut during the feedingoperation of an end from the stack the rock shaft 2 is partially rotated against the action of said spring 30 by means of a lever 31 fixed to the said rock shaft 28, which lever its opposite end or extremity carries a cam foiower roll 32 which operates upon "he irreg liar surface of a cam 33 secured to the u p face of a can end feed secure to and carried by a rtically disposed shaft 35. The can end reed turret as states in the direction indicated by the arrow on 3 of the drawing, and during its norisental rotary movement works over the extension 25 of the bracket 25 and heneath one of the supporting memher 23,'which is cut away at 36, F' 3.. i of the drawing, the thickness of the turret 3 being slightly r sur- J 'tation imparted to the less than the height of a can end, and the said turretis cut away to provide a series of spaced pockets 37. As each pocket moves toward the stack of unlined can ends contained within the opening 23', the separating finger 26 is operated to place the inclined toothed portion 27' thereof between the lowermost can end 24 and the rem'ain der of the stack, which action elevates one side of the stack of can ends above the lowermost can'end and by so doing releases the said lowermost can end of the stack permitting one of the pocket portions 37 of the rotating turret 34 to sweep the released can end from its position beneath the finger 26 and along an arcial path of travel toward a feeding station. The shaft 35 controlling the rotary movement of the turret 34, Fig. 2 of the drawings, is journaled in bearings 38 projected from the bracket 25 and the said shaft receives rotation from the drive shaft 14 through the medium of the mating bevel gears 39 and 40, secured respectively on the lower end of the shaft 35 and on the shaft 14, the turret 34 be ing thus continuously driven from the ro'- shaft 14.

As illustrated in Fig. 4 of the drawings, an unlined can end 24' upon its removal from the stack of unlined can ends is swept ormoved along the upper surface ofthe extension 25' of the bracket 25 by the said turret 34, being controlled in its path of movement by means of the curved guide plate 41 secured to the extension 25' of the bracket 25, which said guide forms a runway leading from the station or position indicated by the reference letter A through an intermediate station B to the feed station indicated by the reference numeral 0', where the unlined can end is positioned into one of the pockets or receptacles of the gasket lining units. During this path of travel or movement of a can end from the stack orholder for the unlined can ends to the position designated by the reference letter C, the cut-out and removed can. end 24 is prevented from vertical displacement by means of an overhanging wall plate 42 mounted upon and inwardly projected from the curved guide plate or wall 41.

One of the gasket lining units is clearly illustrated by Figs. 2, 4, 6 and 7 of the drawings, and the same comprises in the present case a rotatable plunger 43 formed or secured to the upper end of a vertically movable rotatable spindle 44 journaled at 45 in the carrier member 5, which said plunger 43 works within a can end receiving pocket or seat 46 formed in surface of the outstanding circumferential flange 5' of the carrier member 5. The upper inner wall surface of each can end receiving pocket 46 is outwardly beveled as at 4'7, and within the said pocket is freelv ger 43 1S plunger 43 and its associated the upper rotatable the plunger 43, the tapering wall portion of the pocket 46 constituting a centering surface for the unlined can end deposited Within said pocket when the plunpositionedin its lowermost position, Fig. 5 of the drawings. unlined can end is brought by the rotatable turret 34 from the position A into axial alinement with a pocket 46 positioned at the receiving station or position C Fig. 3 of the drawings, the said can end drops or lowers by gravity into the said pocket and is centered relative to the plunger 43 working therein.

In order to provide for the free rotation of the plunger 43 during the raising and lowering movement ofthe same, the means for imparting vertical movement thereto are loosely connected with the spindle 44 of the plunger 54 by the anti-frictional ball bearing means 48, and said lifting device comprises a lifting block 49 which is raised and lowered by the stationary cam member 50, which surrounds the fixed drum member 2, the said lifting block being provided with a cam follower 52 which works within a cam groove 51 of the said cam member 50. A. lug 53 projected from each lifting block 49 Fig. 9 of the drawings, loosely slides on a fixed vertical stud 54 which-is held at 55 to the outer face of the carrier member 5 and retains the cam follower 52 within the groove 51 of the cam member 50 of the fixed member 2. To the spindle 44 of the plunger 43 and intermediate of the length thereof, is fixed a gear 56 which meshes with a stationary gear ring 57 mounted on the fixed drum or member 2 above the cam groove 51 of the cam member 50, Fig. 2 of the drawings, the gear 56 While moving vertically relative to the teeth of the gear 57 during the lifting movement of the spindle 44 is in mesh therewith at all times. It is evident, that as the carrier member 5 advances the parts along the circular path of travel, the gears 56 carried thereby moving over the face of the stationary gear 57 will cause the spindle 44 and the plunger 43 to rotate, and the cam follower 52 carried by the block 49 moving within the cam groove 51 of the stationary cam 50 will raise and lower the plunger 43 during its circular path of travel, the ball bearing connection 48 permitting the described simultaneous movements of the working parts.

The parts comprising each pulp lining unit are mounted within an outstanding circular ledge 58 projected from the outer edge of the container or reservoir 6 andwhich is adapted to partly overlie the plunger 43, Figs. 2, 5 and 6 of the drawings.

n air and pulp nozzle 59 is vertically held by a screw plug58 within the ledge or overhang 58 directly above the plunger 43 When an and in axial alinement with the flan e of a can end 24 when positioned on said p unger. The said .nozzle 59 is connected at its upper end with an air supply pipe 60, which is provided with a hand actuated controlling valve 61 and at its upper end connects or communicates with the interior of the air pressure chamber 20. The lower end of the nozzle 59 projects below the ledge 58 and'the said nozzle is provided with an inlet port 64 which communicates with a horizontally disposed chamber 62 formed in the ledge 58, and which chamber communicates through a port 63 with the interior of the pulp holdmg container or reservoir 6, Figs. 5, 6 and 7 of the drawings, it is understood that the port 64 communicates with the interior bore or passage-way 59 of the nozzle 59. A horizontally reciprocating slide valve 65 is adapted to open and close the port 63 to control the flow of pulp from the pulp chamber of the container or reservoir 6.-to the inlet port 64 of the nozzle 59, and the said valve 65 is reciprocated back and forth to open and close the port 63 through the medium of the valve stem 66. The said stem 66 passes through the base 67 of the container or reservoir 6 and carries at its outer end a yoked extension 68, which supports a cam follower roll 69. 'The slide valve 65 is held normally inwardly pressed to uncover the port 63 by the action of the spring 76 surrounding the stem 66 and which serves to hold the cam follower roll 69 against the face 71 of a stationary cam 72, which surrounds the shaft 10 and is supported by and secured to the drum 2, Fig. 2 of the drawmgs.

As each pulp lining unit is advanced in its circular path of travel by the rotating carrier 5, the cam follower 69 of each unit acts against the cam face 71 and moves the valve 65 longitudinally to open or close the port 63 controlling the flow of pulp from the pulp chamber of the container or reservoir 6, Associated with each air jet nozzle 59 is a vertically disposed spring held gage pin. 73 slidably mounted within a vertical bore of the ledge 58 and in axial alinement with the plunger 43, held downwardly pressed by the action of a spring held within a nut 5 screwed into the ledge 58, and in its lowered position bearing lightly against a can end positioned on the, plunger 43, when the said plunger is in its raised position, Figs. 2, 4, 6 and 7 of the drawings. The gage pin 73 serves to center the positioned can end 24' relative to the plunger 43 and holds the same in proper position during the operation of applying the pulp to the flange thereof.

Inasmuch as the foregoing described interconnected mechanism is in continuous operation during the rotary travel of the carrier member 5, it is required that in case an the said pin being normally.

unlined can end is, not present in any of the pockets or seats for the reception thereof, that the valve 65 'be held against movement so as to close the. port 63 and prevent the escape of the pulp from within the container or reservoir 6 and the flow thereof into the interior of the nozzle 59, and as .it often happens for various reasons that one or more of the gasket linin units will as beneath the can end feedlng station without receiving an unlined end, it is apparent that the discharge of the pulp 6' to the interior of the nozzle 59 must be provided a ainst. For this purpose, there is provided a locking means, Figs. 5 and 8 of the drawings, which comprises a swinging lever 76 fulcrumed at 77 within the ledge 58, the outerend of said fulcrumed lever being loosely held at 78 to the gage pin 73, the 0pposite or free end of the said lever terminating in a hooked extension 79, which works within an opening80 formed through the lower wall of the chamber 62 within which works the slide valve 65. When the free hooked end of the lever 76 is inits raised position, the same is in engagement with the rear wall surface of the slide valve 65 and holds the same locked against movement to close the port 63 leading from the interior of the pulp reservoir 6, Fig. 7 of the drawings. As a pulp lining unit approaches the station C of the apparatus, the plunger 43 is in its lowered position and the slide valve 65 stands in the position indicated by Fig. 5 of the drawings, the hooked extension 79 of the lever 76 at such times resting against the lower wall surface of the slide valve 65, and holding the gage pin 73 upward against the action of the spring 74. As the pulp lining unit is carried past the feeding station (J for an unlined ca end, the valve 65 through the action of the cam follower roll 69 is moved to its extreme forward stroke Fig. 7 of the drawings, which carries the rear face thereof beyond the hooked extension 79 to free the same, allowing the pressure of the spring-'74 to come into action to lower the gage pin 73 its full downward distance, which serves to throw upwardly the'inner or free hooked end 79 of the lever 76 to engage with the rear wall surface of the slide valve 65 and hold the same in its full outward position. If an unlmed can end 24' has been received at the feeding station G into the seat or pocket 46 as the lining unit moves beneath the feedmg station, the same will be gradually raised by the upward movement of the plunger 43 to engage with the lower end of the gage pin 73, the height of the unlined can end being such as to cause the Pin 73 to be raised or elevated a slight distance from the position illustrated in Fig. 7 of the drawings to the position illustrated by Fig.

' 6 of the drawings, which raising of the age lightly against the lower end of the and the projecting thereof onto pin 73 is sufiicient to throw the .hooke extension 79 of the lever 76 downward and out of engagement with the rear wall surface of the slide valve 65, permitting the pressure. of the sprin 76 to throw the slide valve 65 to uncover t e ,port 63. However,'if an unlined can end is not present in the seat of pocket 46, the plunger 43 upon being lifted its full upward stroke will bear only age pin 73, which at that time rests within t e clearance opening 43' of the plunger and the said pin 73 will not be moved upwardly, hence, the hooked extension 79 of the lever 76 will remain in locked engagement with the slide valve 65 and no movement will bepermitted the said valve to uncover the port 63, with the result, that no pulp is permitted to flow from the container or receptacle 6 through the port 63 andth'e interior of the nozzle 59 through the inlet port 64, thereby cutting off the flow of the pulp to the said nozzle.

It will thus be seen that the feeding of the pulp to the nozzle 59. is absolutely controlled in acco'rdance'with the presence or the absence of an unlined can end relative to the pocket or seat 46 of the pulp lining unit, this being an essential factor to be considered in an apparatus of this kind. If"

provision was not made to control the flow action of the pulp in accordance as to whether there is positioned an unlined can end to have pulp applied to the flange thereof, there would be an escape of pulp and a dischar e thereof onto the plunger 43 working' within the seat 'orpocket 46 throughout the entire operation of the machine where an'unlined can end was absent from the jacket 46 of the lining unit.

During the operation of the machine, heated air under com ression is continuously assing throu h t e nozzles 59 on the contro ling valves 0 the pipe lines '60 being open for such purpose, and this flow of air under pressure through the nozzles when] the slide valve 65 is moved to uncoverthe port 63 draws the pulp through the inlet' port 64 to theinterior of the nozzle 59 and causes an atomizing-or spraying of the same the flange of the can end 24' seated on the lunger 43 within the pocket or seat 46, and as the a said plunger 43 is continuously revolving through the action of the previously described mechanism there is sprayed and evenly distributed over the surface of the flange of the positioned can enda layer of pul to form a gasket ring liner 6. On a sufli dient quantity ofthe pulp for the formation .of the desired gasket liner being discharged or deposited onto the flange of the positioned can end, the slide valve 65 operates through the, medium of the cam-ring 71 and the'cam follower roll 69 to close-the outlet port 63 of the pulp holding container or reservoir 6; or, in otherv words, the slide valve 65 is restored to the position indicated by Fig. 7 of the drawings and the hooked extension of the lever 76 thrown upwardly to lock the said valve in such position, Fig. 7 of the drawings.

Each pulp lining unit will be carried approximately one-half of the circumference of the supportin drum member 2 of the apparatus during t e {pulp applying 0 ration, by which time the ange of can en carried thereby will havereceived the proper pulp coating. The action of the cam follower roll 69- whichcontrols the closing action of the slide valve 65 is in such a position rela tive to the cam ring 71 by the time the can end has been lined with the pulp, as to force outwardly the said valve 65 to close the exit port 63 against the escape of pulp from within the container or reservoir 6. However, the stream of heated aircontinues to fiow'through the nozzle 59 and is directed onto the applied pulp until the lined can is removed from the plunger 43, the heated stream thus applied expels the moisture from the pulp and leaves the same as a driled gasket-liner onto the flange of the can en The plunger 43'remains in its raised position until the ulp' linin unit has been carried beyond t e station 1), Fig. 3 of the drawings, the lined can end at such time being held aslight distance above the surface,

ing unit being then in the position dis "vention, and 'I- do-not wish to be understood as limiti ,eorficonfining the invention to such detai 10f construction as to the work by reason of 41, and as the pocket 46 a 46, the working parts of the said pulp linclosed by Fig. 7 of the drawings and with therewith.
